Ingenius Vol. 19, pp. 69-78, 2018 S. Montero, R. Bustamante, A. Ortiz-Bernardin Abstract In the present paper the behaviour of a hyperelastic body is studied, considering the presence of one, two and more spherical inclusions, under the effect of an external tension load. The inclusions are modelled as nonlinear elastic bodies that undergo small strains.

Acta Mechanica Vol. 227, No. 2, pp. 601-615, 2016 S. Montero, R. Bustamante, A. Ortiz-Bernardin Abstract Recently, there has been interest in the study of a new class of constitutive relation, wherein the linearized strain tensor is assumed to be a function of the stresses. In this communication, some boundary value problems are solved using

International Journal of Solids and Structures Vol. 51, No. 3-4, pp. 875-885, 2014 A. Ortiz-Bernardin, R. Bustamante, K.R. Rajagopal Abstract Recently, a very general and novel class of implicit bodies has been developed to describe the elastic response of solids. It contains as a special subclass the classical Cauchy and Green elastic bodies. Within the

Acta Mechanica Vol. 223, No. 9, pp. 1971-1981, 2012 A. Ortiz, R. Bustamante, K.R. Rajagopal Abstract It has been shown recently that the class of elastic bodies is much larger than the classical Cauchy and Green elastic bodies, if by an elastic body one means a body incapable of dissipation (converting working into heat). In

2012 – 2015 Principal Investigator: Roger Bustamante. Co-Investigator: Alejandro Ortiz-Bernardin. Project funded by CONICYT-FONDECYT (Grant Nº 1120011) In the classical theory of continuum mechanics there are two concepts which are considered particularly important, namely stresses and strains. Even though, from an intuitive point of view, we would say that strains are ‘caused’ due to the presence

Principal Investigator: Alejandro Ortiz-Bernardin. In the era of simulation-based design, robust simulation tools are needed to efficiently analyze and accurately predict the performance of solids and structures for loadings and materials with large deformation response. Applications such as metal forming processes, kinematic response of soft biological tissues, earth moving and deep penetration in geotechnical/offshore engineering, and
